maybe you should try a custom rom. no problems over here.

he shouldn't have to try a custom rom to fix something that shouldn't be a known issue. i haven't heard of that problem at all so far. maybe you have a bad device?

yeah its not all the time, but i jsut notice it..strange. almost like a "power saving" thing

It's not your device, mine does the same thing in low building with low reception. Coming from the captivate this phone definitely has worse reception, I would always get 3g on the captivate, but now It bounces from edge to H+. Hopefully they can fix it. Atleast the GPS works.

hmm actually look at settings > wireless & network > mobile networks > enable always-on mobile data
maybe its not checked on? mine was on by default

Its not on because it intelligently toggles data when connected to wifi. I imagine if you toggle it always on, it will...always be on...

sorry, i meant mine was enabled by default.

Switch to a desire HD Rom, I get constant data unlike before on stock

Is your account provisioned for "4G" (aka HSPA+) data access? If you don't know for sure, I'd check with AT&T.

[Q] Lost network connection

I have a strange issue, i lost mobile operator network connection
- aeroplane mode on/off does not help
- manual network search finds all mobile operators in range.
- manual selecting my network operator does nothing, it try to connect but finally display “try again latter”
- Change from 4G to 3G does not help
- Eminency call 112 works fine.
- Phone reset solve the problem.
Do You think that was a mobile network operator problem or my brand new galaxy 5 ?

That new Galaxy 5? That's probably the issue then, since it's not supposed to be out till April or so. But seriously though, have you made any changes to the system? Custom rom? New radio? Etc? Have you tried your SIM in another phone?

Ok, WAS fine, but what about now?

The problem i write about occures only once on nexus 5.
I have this phone only one day. So it hard to say that sim be all right in ohter phone.

I am on AT&T and have this issue too. My SIM was used fine in Nexus 4 for about 10 months. Never had a loss of network issue, but on Nexus 5 randomly, I seem to lose all network connectivity. Tuning airplane mode on-off, Wi-Fi on-off, 2G-3G- 4G toggle, data on-off, all have no effect. The phone acts like it is on a network, but none of the apps can connect. A reboot fixes it.
I am on stock ROM with Franco kernel.

It is not the same problem, because in my case phone log out from network.

My wifi disconnects and phone uses my data when should not

My m8 at some times usually during the night will disconnect my wifi and use my mobile data, which it should not do because in the power settings I have the sleep mode set to off and I have all power saver crap removed with viperone 1.8 I"am just on a limited data plan that I need all of my data for and wasting my mobile data sucks especially when I have wifi to use and pay for home internet that it should be using. Does anyone know why it could be doing this and a fix ? My computer never disconnects from the wifi and I use it many of the same times that the phone disconnects from my wifi, so that leads me to believe its somewhere in the phone and not my wifi. Also I have had a couple other m8's do the exact same thing. I would like to find a fix other than turning my mobile data off. And I do use a lot of data as I have a large number of email addresses added to my phone and have my k9 set to check for new emails every 10 minutes because I rely on it for personal and business use. Anyone have any idea ?

Here is my settings showing sleep mode off and power saving mode off also.

In "wifi advanced settings" do you have the "auto switch to mobile data when wifi is weak" checked off?

No its unchecked but under wifi optimization I have minimize battery usage when wifi is on ? Not sure if that could have an effect but shouldnt because mobile data would use more battery than wifi and that would have the opposite effect to turn wifi off for mobile data which would use more battery power.

I always set it up to remove the power save mode garbage in the venom aroma installer so 100% that is not the issue.

Try Wi-Fi > Advanced > Uncheck "Wi-Fi optimization"
Had the same problem and this fixed it. Haven't noticed any difference in battery life checked vs. unchecked.

Mine is still doing it, so I changed the wifi frequency band from automatic to 5 ghz and rebooted and it connected but some apps could not access data so I changed it to 2.4 ghz only and rebooted it worked ok but its doing it again this time I had to toggle airplane mode to get the wifi back on. I have to toggle airplane mode quite often actually and usually it shows change of sim detected. And some times my mobile data will disconnect and its a ***** to get working again. Maybe I will try going to a verizon corporate store and getting a new nano sim card for it. A verizon dealer could not get a new nano sim to activate before and they ended up getting my old nano sim reactivated which I thought once a sim has been deactivated that they cant reactivate it but apparently they can. I really dont know what else to try other than a new sim card. Anyone ?

Any chance you could temporarily try a different wireless router? Some of these new phones are finicky with some wireless routers... Could be a miscommunication between the phone and router somehow.
Don't really have an explanation, one of my old HTC devices had issues connecting to a specific wireless router, where apple products did not have the problem, and vice versa with a different router.

Having been the case with at least 3 m8's I honestly do not think its the router because It happened with my old moden and router and also with my motorola surfboard SBG6580 modem / wireless router combination that I switched to a couple months ago. And it will also do the same on my girlfriends modem and wireless router. I think there is something in the m8 that is the problem and one other of the m8's was an at&t version. I"am not 100% sure but it may have all been while using viperone, as there really is not much choices for daily driver custom roms especially since elegancia closed its doors. Dont get me wrong tranquil one m8 is not bad and cleanrom is ok but they are no way as easy to customize as viperone is. Years ago I use to like cleanrom for its DE which was barebones the way I like it, good clean and fast. I just dont trust any of the other roms to be bug free enough to be a daily driver. I have just had too many issues in the past with cm dont get me started on them lol, omg was nothing but fix after fix that you had to do nothing like being a Guinea pig lol.

Wi-Fi not connect after phone is woken from sleep mode
Both my wife and I was having the issue with Wi-Fi. I tried everything ,turning off optimization, setting for 2.4ghz,and every other thing listed. Nothing helped until I flashed the firmware from the digitalhigh thread, took 30 sec and fixed Wi-Fi for good on my wife's m8 and mine. I lost nothing in the process except that very annoying Wi-Fi issue. I was then able to set any options like, Wi-Fi optimization and Auto band detect, everything working great!
Here is link to that firmware...

Just downloaded and save to SD card root and rename to "0P6BIMG.zip" and boot to hoot to install.

[Q]i can't get my mobile data and wifi on at same time ...

hello everybody.
i recently got a problem , as we know, in the dev option , there is a setting that enables mobile data on even while Wi-Fi is connected.
i set it on , and then once i connect to wifi the data off immediately.
first of all i thought might be some of my apps interfering the system so i just did factory reset , 0 app installed , i didn't even update the pre-installed apps.
but still same thing , i tried reboot like dozens times, enable disable wifi , enable disable data connection ...etc.
nothing works out...
any idea please ?

So basically you want both on at the same time? Or to change automatically from WiFi to LTE when not in WiFi range?

i wanna them on at same time , just like the screenshots of this thread http://forum.xda-developers.com/s7-edge/help/wifi-data-time-t3349520
i have been googling around , funny thing is i saw few users got them on at same and try to get rid of it and i am desperately try to get them on ...

Can confirm it worked using developers options setting, 4G & WiFi enabled simultaneously yesterday when I read this thread
Just tried it again now and it won't enable 4G unless I disable WiFi
Looks like a bug with the OS, not just you
Report to Samsung and hope for a fix

Just download Google duo app and run.

Excuse me, can i know what is your csc country, i think it's a rom problem
Mine is UAE, are you the same?

I have the same problem on stock nougat without root or any other mods. Didnt recognize it until i created a tasker profile which depends on the wifi. Now i clearly see that there is a problem, cause the profile switches on and off.
I have already disabled bluetooth/wifi scan, smart network switch and set the wifi to always on - nothing helps...

I have the same problem and I have a (BTU) CSC. I thought it was to do with my battery saving apps and RAM optimisers, so for example for me L Speed but for other it may be Greenify, BatteryCare etc. These apps contain a feature called Aggressive Doze which causes things to shut down and close off while phone has been left inactive for more than 6 mins because if you notice our WiFi doesn't turn off straight away. I would definitely like to whitelist the WiFi application but I am unsure on how to do so. It's really annoying when trying to download big files and WiFi constantly keeps turning off and me having to keep screen on all of the time.
This could be completely wrong but please let me know if you and other guys on this thread are using such apps
